It is to be understood that the drawings described are for purposes of illustrating only some embodiments of the invention and not all embodiments, and that other designs may be devised by those skilled in the art without the use of the inventive faculty.

Fig. 1 is the structure schematic diagram of the utility model relates to a vertical lifting liquid medicine quantitative filling device.

Detailed Description

The present invention will be further described with reference to the following detailed description.

At present, the filling modes for medicine liquid in China are two major types, namely peristaltic pump filling and plunger metering pump filling.

The working principle of the peristaltic pump is as follows: the peristaltic pump is composed of a peristaltic pump driver, a peristaltic pump head and a peristaltic pump hose, the peristaltic pump is driven by the peristaltic pump driver to operate, the rollers in the peristaltic pump head replace fingers, and the peristaltic pump works by means of pumping efficiency generated by alternately extruding and releasing the rollers along an elastic hose. When the flow output of the fluid extruded in the pipe is generated, and the pipe is restored to the original state by the elasticity of the pipe after the pressure disappears, the volume is increased, vacuum is generated, and the fluid is sucked. The filling by a peristaltic pump has the following disadvantages: the long-time filling leads to peristaltic pump silica gel hose extrusion deformation, leads to the filling precision poor, if frequently change lead to use cost higher.

The working principle of the plunger type metering pump is as follows: the plunger metering pump consists of a pump sleeve, a rotary valve, a metering rod, a liquid inlet and a liquid outlet. The port of the rotary valve is aligned with the liquid inlet, the metering rod moves linearly downwards to generate negative pressure and suck liquid, the port of the rotary valve is aligned with the liquid outlet, and the metering rod moves linearly upwards to generate positive pressure and discharge liquid, which is the working principle of the plunger type metering pump. Disadvantages of plunger metering pump filling: the installation requirement of the pump is higher, namely the concentricity requirement of the rotary valve and the pump body is higher, and the rotary valve is easy to block once the eccentricity is generated; during operation, the metering rod and the pump sleeve generate heat due to friction, and particles are generated to pollute the medicine.

As shown in fig. 1, a device for filling a liquid medicine in a fixed amount by lifting the liquid medicine in a longitudinal direction includes a liquid inlet pipe 1, a liquid outlet pipe 2 and a pump chamber 12, wherein the pump chamber 12 is communicated with the liquid inlet pipe 1 and the liquid outlet pipe 2, a lower valve 13 is disposed on the liquid inlet pipe 1, and an upper valve 8 is disposed on the liquid outlet pipe 2. The horizontal piston 11 is arranged in the pump cavity 12, the tail end of the piston 11 is provided with the push-pull rod 5, the push-pull rod 5 drives the piston 11 to move left and right in the pump cavity 12, the upper valve 8 comprises a T-shaped valve a10 which is vertically arranged and a base a9 which is matched with a bottom end convex column of a T-shaped valve a10, and the lower valve 13 comprises a T-shaped valve b15 which is vertically arranged and a base b14 which is matched with a bottom end convex column of a T-shaped valve b 15.

4 fixing rods 3 and end covers 4 are arranged on the outer side of the pump cavity 12, the end covers 4 are fixedly arranged on the 4 fixing rods 3, a linear bearing 6 is arranged in the center of each end cover 4, and the push-pull rod 5 penetrates through the linear bearing 6.

An elastic sealing ring 7 is arranged between the piston 11 and the inner wall of the pump cavity 12.

In actual operation, when the push-pull rod 5 drives the piston 11 to move rightwards in the pump cavity 12, negative pressure is formed in the pump cavity 12, the bottom end convex column of the T-shaped valve a10 is pressed on the base a9, the T-shaped valve b15 is sucked up, and the liquid medicine in the liquid inlet pipe 1 enters the pump cavity 12; when the push-pull rod 5 drives the piston 11 to move leftwards in the pump cavity 12, the liquid medicine in the pump cavity 12 is squeezed, the bottom end convex column of the T-shaped valve a10 is jacked up from the base a9 by the liquid medicine, the liquid medicine is squeezed and output from the liquid outlet pipe 2, the T-shaped valve b15 is propped downwards, the bottom end convex column of the T-shaped valve b15 is pressed on the base b14, and the liquid medicine in the liquid inlet pipe 1 cannot enter the pump cavity 12.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
